I plan to be doing some traveling soon where I will not have internet connectivity and will want to post a lot of information to my blog. So I need something that will let me post and edit, then get connected to upload. I have a list of must have features:

• Performance: It does not matter what cool features the off line blog editor has. It must be reliable. I do not want it to freeze, loose posts, post duplicates, etc. It does not matter so much what it does, as long as it does it well.
• No Files: I don’t want to have to save every post as a file. They need to be stored in the application.
• Automatic posting: I should be able to write, write, write offline. Then when I get to an internet connection, I need to press upload, and viola! everything is on the server.
• Needs to support categories
• WWYSIWYG editing
• Be able to add pictures offline, and have them uploaded.
• Support WordPress
• Support Windows
• Spell Checker

I also have a list of Highly Desired features:

• Hindi support for posting – I’m trying to learn Hindi, so some of my posts will have Hindi in them.
• Download entire blog – useful for backups
• IMage conversion – take BMPs, and GIFS and convert them to jpgs for instance
• Thumbnail creation – I have a 6 megapixel camera, and I plan to get a 10 mega pixel camera today. So, I need something that can easily take those pictures and convert them to something smaller.
• Templates – Some blog postings should use a template, say for movie or book reviews

Nice to have features:

• Trying to learn Japanese and German for upcoming trips. This is a temporary thing, so not as important as the Hindi support above.
• Download comments from a blog, allow for them to be deleted/approved offline
• Amazon search to put products in the blog with my Amazon affiliate code.

I’m sure as I review several offline blog editors, I will find additional features that I will need.
